The aim of the present investigation was to study the role of Al2O3 in the Li2O–CaO–P2O5–SiO2 bioactive glass for improving the bioactivity and other physico-mechanical properties of glass. A comparative study on structural and physico-mechanical properties and bioactivity of glasses were reported. The structural properties of glasses were investigated by X-ray diffraction, Fourier transform infrared...
A compact aperture-coupled dual segment rectangular dielectric resonator antenna (ACDS-RDRA) is described in this paper. The antenna consists of Teflon (εr = 2.1) as lower segment and liquid phase (glass) sintered Barium Strontium Titanate (BST) namely Ba0.5Sr0.5TiO3 (εr = 27) as upper segment. 10 wt% of PbO-BaO-B2O3-SiO2 glass was added to lower the sintering temperature from 1050 °C to 800 °C and...
A filleted rectangular dielectric resonator antenna (FRDRA) is described in this paper. The antenna consists of Teflon (εr = 2.1) as lower segment and 10 wt% of glass (PbOBaO-B2O3-SiO2) sintered Barium Strontium Titanate (BST) namely BSTG10 (εr = 27) as upper segment. Glass was added to lower the sintering temperature from 1050 °C to 800 °C and increase the permittivity of BST. The FRDRA provides...
